I have been studying these seforim and noticed the text is marked with trope. However, since these seforim are not read publically, what is the proper cantillation? Like neviim?
The Syrian Sephardic tradition reads the taamim of Daniel and Ezra/Nehemia (as well as Job 1-2, Ecclesiates, and Chronicles) in the same melody as Ruth. This is sung in a precious Middle-Eastern scale known as Hoseni, which, among other special occasions, is used by the Syrians for the Torah reading during Shavuot. You can hear a recording of this melody, sung by Hazzan Haim Daya, here.
As a side technical note, this might be a rather challenging melody for those unaccustomed to singing Middle-Eastern music, as Hoseni has contains two quarter-tones not found in Western music.
